Vol. 25: Microcontrollers and Arduino
Give your gadgets a brain! Previously out of reach for the do-it-yourselfer, the tiny computers called microcontrollers are now so cheap and easy to use that anyone can make their stuff smart. It's called "physical computing" -- with a microcontroller, your gadget can sense the environment, talk to the internet or other gadgets, and make things happen in the real world by controlling motors, lights, or any electronic device. The Arduino is an easy-to-use microcontroller board -- it's like an R&D lab on your kitchen table for prototyping any gadget. We show you how to make one, and how to use Arduinos and other microcontrollers to make an automatic yogurt maker, a vintage Skype telephone, a gumball machine that recognizes your secret knock, and more. Plus, make a Helicopter Rocket, portable solar power pack, gourmet Sous Vide food cooker, treadmill desk, and more fun DIY projects. On newsstands now! » BUY OR SUBSCRIBE

Where it appears:
The Chinese Windlass, Page 171
The Error: Volume 26's Make Amends incorrectly corrected the equation values in Volume 25's Remaking History. Aargh! The crank length (a radius) is 6" as originally stated, but the radius of the large barrel is 1.5". The value of the expression is therefore 96, not 48.
Where it appears:
Sous Vide Immersion Cooker, Page 107
The Error: In Volume 25s Sous Vide Immersion Cooker, page 107, we listed the wrong clear acrylic box from Amazon. The correct part number is #B000NE9VJE.
Where it appears:
Secret Knock Gumball Machine, Page 95
The Error: Secret-Knock Gumball Machine" (MAKE 25), on page 95, the part number listed for the clear plastic globe from 1000bulbs.com was incorrect and should have read #3202-08020.
Where it appears:
Primer: Make and Use an Arduino, Page 65
The Error: The second paragraph on page 65 should read:
"To connect the chip to power and ground, jumper [...] J-7 to right ground, and J-9 to right power (Figure G)."
The print version had power and ground reversed for pins J-7 and J-9. Figure G is correct.
